HARROW.

Original application filed July 8, 1918, Serial No. 243,848.

Serial No. 266,836.

To all whom it may concern:

Be it known that I, WVILLARD 0. LONG, a citizen of the United States,residing at Mansfield, in the county of Richland and State of Ohio, haveinvented a new and useful Harrow, of which the following is aspecification.

This invention relates to barrows and is more especially a division ofan application filed by me on July 8th, 1918, Serial Number 243,848.

One of the objects of the invention is to provide a simple and efficientadjustable connection between the harrow and its draw bar or connectingmeans.

WVith the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts which will be hereinafter morefully described and pointed out in the claims, it being understood thatvarious changes may be made in the construction and arrangement of theparts without departing from the spirit or sacrificing any of theadvantages of the invention as set forth in the appended claims.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings- Figure l is a perspective view of the harrow and itsconnections.

Fig. 2 is a view partly in section and partly in elevation of theconnection between the harrow and its draw bar.

Fig. 3 is a section on line 33 of Fig. 2.

Referring to the figures by characters of reference, A designates aportion of a plow structure provided with a short shaft 11 journaled inthe lower portion of a segment 5 and adapted to be actuated by a handlever 14. A sleeve 21 is secured on the shaft 11 and has a tubularextension 22 in which is secured an arm or draw bar 23.

The harrow is adapted to be connected to the lower or rear end of thearm or bar 23 and includes parallel angle strips 25 in which are securedthreaded stems 26 projecting from the teeth 27 of the harrow. Nuts 28engage the stems above and below the strips to form solid connectionsbetween Specification i LettsrsPfltev-t Patented Sept'30 Divided and.this application filed December 14,

the teeth and strips. Certain of the stems are used for securing anglebrackets 29 to the strips 25 nd these brackets, in turn, are connectedby strips 30. The stem of one tooth on each strip 25 can be used toengage the foot of a standard 31 and secure it to the strip. Thestandards are connected by parallel strips 32 pivotally attached theretoand longitudinal slots 33 are formed in the standards. A brace 31 isconnected to one of the strips 32 and is adjustably secured to theslotted portion of the rear standard 31, thus to hold the strips 25against rotation about their individual longitudinal axes.

U-clamps 35 are interposed between the other standards 31, which are inpairs, as

shown, and these clamps embrace the arm or bar 23 and are held thereonby bolts 36 which also serve to secure the clamps adj ustably to thestandards.

"Where the harrow is used with a tractor plow, it is slidably connectedto the bar 23. This can be done by placing spacing sleeves 39 on thebolts 36 so as to prevent the clamps 35 from gripping the arm 23.Another clamp 35 without the spacing sleeve can be placed on the rearend portion of the bar 23 and will prevent the arm from sliding forwardtoo far relative to the harrow. \Vhcn the tractor is backed, however,the arm 23 will slide in the clamps 35 having the spacing sleeves and,if the arm or bar 23 is held against movement, its tendency will be toelevate the harrow during this rearward movement because of itsinclination downwardly and rearwardly, as shown. The slidable connectionbetween the parts has been shown in Fig. 2.

lVhat is claimed is:-

1. The combination with a plow structure and a draw bar carried thereby,of a harrow structure connected to the draw bar and shiftable therealongto an elevated position by the backing of the plow structure.

2. The combination with a plow structure, of a harrow structure, andslidably connected Ireans connecting said structures for elevating theharrow structure when the plow structure is backed.

3. The combination with a plow structure, of a harrow structure, meansconnecting said structures for elevating the as my own, I hate heretoaflixed my signalharrow structure When the plow structure ture in thepresence of two Witnesses. I is backed and means for shifting said con-I necting means to elevate the ham-0W strucl WILLARD O tureindependently of the. backing move- Witnesses:
